Background: In congenital malformation of the thumb index finger pollicization is a proven method for constructing a new thumb all over the world.

Methods: A series of 19 pollicizations in 15 patients is presented. In all cases of index finger pollicization the method of Buck-Gramcko is used and the functional outcome is evaluated after Percival's method. Three special cases are described in detail and the preoperative evaluation with a CT-angiography in cases of complex malformations (case 3) for better planning of the surgical steps is recommended. The importance of parent's information soon after giving birth to a child with thumb hypoplasia is described in detail as the postoperative management.

Results: In children with bilateral deformities of the hand the surgery can be performed in one session, in only 2 cases a second operation was necessary. The postoperative results were excellent and good (Percival's measurement) and the children are now able to perfectly use their affected hand in their day-to-day activities.

Conclusion: Buck-Gramcko's method of pollicization in congenital thumb malformation gives excellent results. The preoperative planning and exactly following the four key steps is as important as the postoperative management.

Introduction: Flexor tendon injuries are common and require surgery. Acellular dermal matrix (ADM) is a natural graft used to repair tissues, though infections represent the primary cause of its therapeutic failure. In this study, zinc oxide nanoparticles (ZnO-NPs) were coated on the ADM in order to add antibacterial potential as well as enhance healing properties.

 To evaluate the safety and effectiveness of a modified pull-out suture technique in patients undergoing primary repair surgery for injuries to the flexor tendons of the fingers with Total Active Motion (TAM) as the primary outcome.  A total of 29 patients (38 fingers) were chosen from both sexes, aged between 18 and 65 years with clean acute tendon laceration occurring within 15 days, in the Verdan's zone II of flexor tendon in the hand, when only the deep flexor tendon was sutured, either associated or not with digital nerve injury. The patients were operated on using the proposed technique and evaluated at 3, 9 and 24-weeks PO.

Background: There are no reports that detail clinical outcomes using the 8-strand suture techniques and early active mobilization. We aim to report the outcome of using an 8-strand double-cruciate core suture followed by early active motion without finger splinting.

Materials And Methods: Thirty-five patients with 41 affected digits were operated and followed up for at least 6 months.

Background: Hand zone II flexor tendon repair had been associated with many complications thereby it was previously called no man's land. Although there is some agreement on the primary repair of flexor tendons in this area, it is challenging due to certain complications. We compared the six and four-strand techniques in the repair of flexor digitorum profundus (FDP) tendons of zone II.

 Flexor tendon injury zone V is a multicomponent soft tissue injury involving tendons, nerves, and vessels. Outcome assessment of repair thus requires evaluation of the hand as a whole rather than solely evaluating tendon function. The purpose of this Preferred Reporting Items for Systematic Reviews and Meta-Analyses -compliant systematic review was to identify and assess the components of outcome measures used in flexor zone V.
